Question

---

Example:

d:\folder1\folder2\assets\images\62f9a0f4-98b9-4dd0-8047-ed1a3cc306cf.png

In my case,I just need \\images\\62f9a0f4-98b9-4dd0-8047-ed1a3cc306cf.png from the path in Javascript.

Answer 1

Not the ideal solution, but gets the work done. I had to escape the \\ while creating the string

var arr = "d:\\folder1\\folder2\\assets\\images\\62f9a0f4-98b9-4dd0-8047-ed1a3cc306cf.png".split("\\");

    var length = arr.length, path = "\\" + arr[length-2] + "\\" + arr[length-1];

    console.log(path);

Answer 2

This should do it:

 var str = "d:\\\\folder1\\\\folder2\\\\assets\\\\images\\\\62f9a0f4-98b9-4dd0-8047-ed1a3cc306cf.png"; var ret = str.split("\\\\").reduce((p,c,i,arr) => {if(i >= arr.length - 2){return (p?("\\\\"+p+"\\\\"):"")+c}}); console.log(ret); 

Answer 3

var url = window.location.pathname;
var filename = url.substring(url.lastIndexOf('/')+1);
var indxend = url.lastIndexOf('/')-1
var folderName =url.substring(0,indxend).substring(url.substring(0,indxend).lastIndexOf('/')+1);

Answer 4

Give this a go:

 var path = 'd:\\\\folder1\\\\folder2\\\\assets\\\\images\\\\62f9a0f4-98b9-4dd0-8047-ed1a3cc306cf.png'; var parts = path.split('\\\\'); var file = parts.pop(); var fileAndPar = parts.pop() + '\\\\' + file; console.log(fileAndPar);
